-.TH APLAYMIDI 1 "15 Feb 2004"
-
-.SH NAME
-aplaymidi \- play Standard MIDI Files
-
-.SH SYNOPSIS
-.B aplaymidi
-\-p client:port[,...] [\-d delay] midifile ...
-
-.SH DESCRIPTION
-.B aplaymidi
-is a command-line utility that plays the specified MIDI file(s) to one
-or more ALSA sequencer ports.
-
-.SH OPTIONS
-
-.TP
-.I \-h, \-\-help
-Prints a list of options.
-
-.TP
-.I \-V, \-\-version
-Prints the current version.
-
-.TP
-.I \-l, \-\-list
-Prints a list of possible output ports.
-
-.TP
-.I \-p, \-\-port=client:port,...
-Sets the sequencer port(s) to which the events in the MIDI file(s) are
-sent.
-
-A client can be specified by its number, its name, or a prefix of its
-name. A port is specified by its number; for port 0 of a client, the
-":0" part of the port specification can be omitted.
-
-For compatibility with
-.B pmidi(1),
-the port specification is taken from the
-.I ALSA_OUTPUT_PORTS
-environment variable if none is given on the command line.
-
-.TP
-.I \-d, \-\-delay=seconds
-Specifies how long to wait after the end of each MIDI file,
-to allow the last notes to die away.
-

-.TH ARECORDMIDI 1 "17 Sep 2007"
-
-.SH NAME
-arecordmidi \- record Standard MIDI Files
-
-.SH SYNOPSIS
-.B arecordmidi
-\-p client:port[,...] [options] midifile
-
-.SH DESCRIPTION
-.B arecordmidi
-is a command-line utility that records a Standard MIDI File from one or
-more ALSA sequencer ports.
-
-To stop recording, press Ctrl+C.
-
-.SH OPTIONS
-
-.TP
-.I \-h,\-\-help
-Prints a list of options.
-
-.TP
-.I \-V,\-\-version
-Prints the current version.
-
-.TP
-.I \-l,\-\-list
-Prints a list of possible input ports.
-
-.TP
-.I \-p,\-\-port=client:port,...
-Sets the sequencer port(s) from which events are recorded.
-
-A client can be specified by its number, its name, or a prefix of its
-name. A port is specified by its number; for port 0 of a client, the
-":0" part of the port specification can be omitted.
-
-.TP
-.I \-b,\-\-bpm=beats
-Sets the musical tempo of the MIDI file, in beats per minute.
-The default value is 120 BPM.
-
-.TP
-.I \-f,\-\-fps=frames
-Sets the SMPTE resolution, in frames per second.
-Possible values are 24, 25, 29.97 (for 30 drop-frame), and 30.
-
-.TP
-.I \-t,\-\-ticks=ticks
-Sets the resolution of timestamps (ticks) in the MIDI file,
-in ticks per beat (when using musical tempo) or ticks per frame
-(when using SMPTE timing).
-The default value is 384 ticks/beat or 40 ticks/frame, respectively.
-
-.TP
-.I \-s,\-\-split\-channels
-Specifies that the data for each MIDI channel should be written to a
-separate track in the MIDI file.
-This will result in a "format 1" file.
-Otherwise, when there is only one track,
-.B arecordmidi
-will generate a "format 0" file.
-
-.TP
-.I \-m,\-\-metronome=client:port
-Plays a metronome signal on the specified sequencer port.
-
-Metronome sounds are played on channel 10, MIDI notes 33 & 34 (GM2/GS/XG
-metronome standard notes), with velocity 100 and duration 1.
-
-.TP
-.I \-i,\-\-timesig=numerator:denominator
-Sets the time signature for the MIDI file and metronome.
-
-The time signature is specified as usual with two numbers, representing
-the numerator and denominator of the time signature as it would be
-notated. The denominator must be a power of two. Both numbers should be
-separated by a colon. The time signature is 4:4 by default.
